Design of a multi-diameter in-line cleaning and fault detection pipe pigging device

摘要

This work presents an innovative approach for the design and development of Pipeline Inspection Gauge (PIG) which can clean / inspect pipes from 6" up to 14" with a simple change of shirts using the latest technologies such as Ultra Sonic Sensors for the pipelines of palm oil, water, and oil/ gas industries through the creation of a simulation tool capable of generating simulated images from pipeline using Arduino Software for highest accuracy and precision inspection to protect the environment and equipment from any unexpected accident. There are several DC motors powered by an installed battery to move the PIG inside the Pipeline. Radio transmitter is used to elongate the distance of investigation by the mean of reduction of the number of individual pigging processes to save time and cost for companies. The DC controller used to control each individual DC motor to rotate synchronizely producing linear movement of The PIG inside the Pipeline. Fluid hammer effect is another factor which has been considered during designing this pig. To avoid such case to occur the design has been revised and several arms have been devised around the robot to maintain the speed and position of pig all the way through the pipeline.
